January 29, 2023 - This library enables you to use Interrupt from Hardware Timers on an ESP32-S2-based board. These ESP32-S2 Hardware Timers, using Interrupt, still work even if other functions are blocking.

This library enables you to use Interrupt from Hardware Timers on an ESP32, ESP32_S2-based board to create and output PWM to pins. Becayse this library doesn't use the powerful hardware-controlled PWM with limitations, the maximum PWM frequency ...

Why would you attempt to register an interrupt again with timerAttachInterrupt()? For a simpler Arduino way to do this, use Ticker. It works great and takes care of the timer setup/teardown. https://github.com/espressif/arduino-esp32/blob/master/libraries/Ticker/examples/Blinker/Blinker.ino ·
